Beschichtungszusammensetzungen auf der Basis von Epoxidgruppen enthaltenden Silanen

摘要

The invention relates to a coating composition, comprising at least one silicon compound (A), said compound (A) having at least one radical which cannot be split off hydrolytically, which is directly bonded to Si and which contains an epoxide group, a particulate material (B) selected from oxides, oxide hydrates, nitrides and carbides of Si, Al and B and of transition metals, which has a particle size of between 1 and 100 nm, a compound (C) of Si, Ti, Zr, B, Sn or V and at least one hydrolysable compound (D) of Ti, Zr or Al in the following proportions: 1 mole of the silicon compound (A), 0.42-0.68 mole of the particulate material (B), 0.28-1.0 mole of the compound (C) and 0.23-0.68 mole of the compound (D).
